Islam Times - A political expert says the Mossad and the Mujahedin-e Khalq Organization (MKO) terrorists carried out the assassination of the Iranian scientist Mostafa Ahmadi Roshan after clearance from handlers in Washington.

“Ultimately the author must have been Washington” as “none of the groups would dare carry out this high-profile hit without clearance from handlers in Washington,” wrote Finian Cunningham in the Global Research.

Cunningham added that the US, along with “British MI6, Mossad and local proxies” has been orchestrating a campaign of terrorist subversion in Iran with the aim of overthrowing the establishment of the Islamic Republic, and “this is the real reason for the contrived confrontation over Iran's nuclear activities.”

“The US covert war against Iran raised the stakes even higher today with the assassination of yet another nuclear scientist, with some analysts saying that the Islamic Republic is being pushed into a corner to either back down in its confrontation with the US or retaliate - the latter most certainly triggering an all-out war,” wrote Finian Cunningham.

On Wednesday morning, an unknown motorcyclist attached a sticky bomb to Ahmadi Roshan's car near Allameh Tabatabaei University in Tehran. Ahmadi Roshan was immediately killed and his driver, who had sustained injures, passed away a few hours later in hospital.

Ahmadi Roshan was a Sharif University of Technology chemical engineering graduate and served as the deputy director of marketing at Iran's Natanz nuclear facility.

In November 2011, some of the US presidential hopefuls openly called for conducting covert operations ranging from assassinating Iranian nuclear scientists to launching a military strike on Iran as well as sabotaging Tehran's nuclear program.

These are not idle threats, as on November 29, 2010, Shahriari and Fereydoun Abbasi were targeted by terrorist attacks; Shahriari was killed immediately and Dr. Abbasi, the current director of Iran's Atomic Energy Organization, only sustained injuries.

Professor Masoud Ali-Mohammadi, another scholar at Tehran University, was also assassinated by a booby-trapped motorbike in the Iranian capital in January 2010.
